The present invention concerns powder compositions including iron-containing powders, additives, lubricant and flow agents. The powder compositions essentially consist of iron-containing particles having additive particles bonded thereto by a molten and subsequently solidified lubricant for the formation of aggregate particles and from about 0.005 to about 2 percent by weight of a flow agent having a particle size below 200 nanometers.
La présente invention concerne des compositions pulvérulentes comprenant des poudres à teneur en fer, des additifs, des agents fluidifiants et lubrifiants. Les compositions pulvérulentes sont essentiellement composées, d'une part, de particules à teneur en fer présentant des particules d'additifs liées à elles par l'intermédiaire d'un lubrifiant fondu puis solidifié pour former des particules en granules et, d'autre part, de 0,005 environ à 2 pour cent environ en poids d'un agent fluidifiant présentant un calibre inférieur à 200 nanomètres.
